"valve c n r ti and bolts indicated at Q. The front lower portion of the tubular gas conduit is set in the brick work A? of the furnace, as best shown in Fig.1, the sides oeing set in the brick work shown at A, A in Fig. 3.

nc L ier portion of the & conduit-is covered fracfor} material, preferably ofa sandy character. aslndicated at P, Fig. 1.

' comp tmcnts formed-by toe oblique pal tition's G, G,' and an escape for water being provided through the outlet pipe indicated at .L. The accumulation of sediment in the lower inner end of the gas port water back K rainst; partly by the truncation of water back, as 'r G" and. partly by the provii q or Jack and connnunicating with J having a valve J The iznicates through a branch 'zaving van/e K- with an auxiliary waply pipe I having a valve I and coination with the interior of the water bacli through branches having delivery nozl", which, like the nozzles H, are

.to the lateral compartments formed titions in the water back. The no of sediment in the lowerend of the water back is avoided by opening the cock of the outflow pipe J permitting a the pipe J; when to stir up the sediment, or for auy other reason, an unusually energetic how of water is desired. water is introduced through the pipe J, as well as the nozzles I l. by opening the cock I and-cock K in another application filed. by me Janu "I. ltlli'}, Serial Number 536,779, I have described a water back for gas ports having, with regard to the circulating mechanism, many features which are common also to the structure above described. So far as the circulating means are in themselves new they are claimed in my said other application and only intended to be claimed in this case as applied to the special structure of the tubular gas conduit. 1

Having now described my invention what claim as new and desire to secure by Letters Patent is- 1. In. combination with a regenerative open hearth furnace a gas port consisting of a double walled metallic tube constituting a water back and lined with refractory material, said tube extending into the furnace through the outer wall thereof and having its front bottom" portion and its ning into the lower end 'nnount of water to pass outand closing the cock J ing a water back and lined with refractory material, said tube extending into the furnao through the outer wall thereof and ha v ng its front bottom ortion and its sides .set in the brickwork o the furnace and a, covering of refractory material over 1ts top,-

a vertical gas conduit also consisting of a double walled metallic tube linedwith refractory material, said conduitconnecting with the gas port at its top and with the gas generator at its bottom and means for causing water tocirculate in both the gas port and the vertical gas conduit.

A tubular water back for a gas port having longitudinal internal partitions forming chambers open at both ends in combina non with water inlet nozzles directed mto the body of the water back by said partithe rear ends of the spaces separated from t-ions and an outlet for water. and steam at the rear top of the water back.

l. A tubular Water back for a gas port having longitudinal internal partitions forming chambers open .atbot-h ends'and having its lower front lateral edges formed obliquely incombination with water inlet nozzles directed into the rear ends of the spaces separated from the body of the water back by said partitions, an outlet for Water and steam .at the rear top of the water back and a separate outlet of reduced area opening into the lower front portion of the water back.

a 5. A tubular water back for a gas 'port having longitudinal internal partitions forming chambers open at bot-h ends incombination with water inlet nozzles directed into the rear ends .of the spaces separated from the body of the water back by said partitions, an outlet for water and steam at the rear top of the water back and a separate outlet of reduced area opening intolthe lower front portion of the water-back and means for forcing water directly into the lower front portion of the water back.

6. In combination with a regenerative furnace havin a as )0rt a as coni b b v 7 a duit connecting said port and a regeneration said conduit consisting of a double walled metallic tube lined with firebrick, a water conduit connecting the top and bottom of the water space in the gas conduit, a water injection nozzle directed downward into the water pipe and means for passing off surplus water from the water space of the gas con- 7, In combination with a regenerative furnace having "a gas port, gas conduit surplus water from connecting said port and a regenerator, said conduit "consisting of a double walled me tallic tube lined with firebriclgfja'water conduit connecting the top'and "bottom of the water space in the gas conduit, a water injection nozzle directed downward into thewater pipe, a separate waterinijection nozzle directed into the bottomtof the water space in the gas conduit, and means for passing of gas conduit.

8. In combination with a. regenerative conduit consisting of.a double walled methe water space of the 'water' space in the gas conduit, a water ingect-ion nozzle directed downward into the waterpipe, a separate water injection nozzle directed into the bottom of the water space in the gas conduit, a restricted water outlet I from'the bottom of the said bottom of the water space and a main water outlet from the top of the-water space. t v v WOOD, 31m.
